Abstract

Complete dentures are one of the most basic treatment methods for the treatment of edentulous patients. The manufacturing process of traditional complete dentures goes through the steps of taking primary impressions, secondary impressions, jaw relation record, trying in wax denture, and final denture insertion. Multiple visits and complex manufacturing procedures are required, and errors may occur in each step. With the development of digital technology, manufacturing steps have been reduced by introducing digital technology to the denture treatment process. In the process of manufacturing dentures by introducing a digital process, a more precise work is possible using Computer-Aided Design, and it is possible to shorten the period of labor and reduce the number of visits. In this case, the anterior teeth arrangement of the patient's existing dentures was transferred to the final dentures using a digital method. After taking impression, try-in dentures were digitally fabricated and tried in the oral cavity to evaluate their retention in the oral cavity. Final dentures were manufactured by milling process. The number of visits was reduced, satisfactory retention and stability of dentures were obtained, and aesthetic recovery was achieved.

총의치는 무치악 환자의 치료에 있어 가장 기본적인 치료방법 중 하나이다. 전통적인 총의치의 제작과정은 예비인상 채득, 최종 인상 채득, 악간관계 채득, 납의치 시적, 의치 장착의 단계를 거치게 된다. 여러 번의 내원 과정과 복잡한 기공 과정이 필요하며, 각 단계별로 오차가 발생할 수 있다. 최근 디지털 기술이 발전함에 따라 총의치 치료과정에도 디지털 기술이 도입되고 있으며, CAD를 이용해 더 정밀한 작업이 가능하며 기공 시간을 단축시키는 것을 물론 환자의 내원 횟수도 줄일 수 있다. 본 증례에서는 디지털 방식을 활용하여 환자의 기존 의치의 전치 배열을 최종 의치로 이행하였다. 3D 프린터를 이용해 시적 의치를 제작하여 환자에게 시적하여 구순 지지도와 전치부 배열을 포함한 심미성 및 구강내 유지력을 평가 후 최종 의치 제작하였다. Computer-Aided Design/Computer-Aided Manufacturing 기술을 활용하여 내원 횟수를 줄이는 동시에, 만족할 만한 의치의 유지력 및 안정성을 얻었으며 심미적인 회복을 이루었기에 본 증례를 보고하고자 한다.
